WebRayleigh flow refers to frictionless, non-Adiabatic flow through a constant area duct where the effect of heat addition or rejection is considered. Compressibility effects often come into consideration, although the Rayleigh flow model certainly also applies to incompressible flow. For this model, the duct area remains constant and no mass is added within the duct.

"WebThe resulting relation is shown below where L* is the required duct length to choke the flow assuming the upstream Mach number is supersonic. The left-hand side is often called the Fanno parameter. Equally important to the Fanno flow model is the dimensionless ratio of the change in entropy over the heat capacity at constant pressure, c p . " - Rayleigh flow relations
